The putting stroke that is best depends upon the individual. So try them
all deciding which is best for you. Shoulders controlling: With the wrists
in a locked position and with the shoulders and arms working in unison
control, the club throughout the stroke.

The shove type: The word shove is misleading. An actual shove is illegal.
It's only a feel. What gives this shove feel is the stroke is made with
a very short backswing and a long followthrough. The advantage of this
type of stroke is the shorter the backswing, the less chance of error.

The grip most certainly will influence the clubhead, but any type
of grip that will keep the wrists from opening or closing the blade
is a good grip regardless of how the hands grip the club. Whatever grip
is chosen the thumbs should be on top. The thumbs are the feelers and
being on top one can feel if the blade is square. Any stroke that holes
the ball consistently is a good putting stroke. Regardless of the style
of the stroke the putter head should never be taken to the outside of
the target line on the backswing.

Finally, I have a drill that may work for you when practicing your
putting stroke called the Tap stroke. To learn this stroke pretend there
is a tack stuck in the back of the ball and when you make your stroke
have the putter head drive the tack further into the ball. This will
encourage you to hit the ball with more authority which with this shorter
stroke there will be less chance of the putter blade getting out of
what is called square position. So start getting "Tacky" on
the greens!
